Too large

I was excited to try this new toothbrush. I like the concept and the style of it. However, I found the toothbrush head much too large. I could not properly reach and clean my back teeth in particular. I will not continue to use this toothbrush because of that.

Hurts my teeth

I tried this product for 2 weeks. Towards the end of the 2 weeks my teeth and gums were sore. I wasn't really sure why, so I stopped using the battery powered toothbrush and within 2 days I was back to normal. I decided to retry the power toothbrush and within a few days my mouth hurt again! Perhaps I'm too sensitive to the vibrations, I'm not sure, but I have resorted to using my old faithful manual toothbrush.

Feels Like It’s Not Working

I am personally not a fan of the Colgate Optic White zpowered Toothbrush. I do not feel it working at all while I am brushing my teeth. I hope I am wrong and won’t have cavities when I go see my dentist. Not a fan of this product unfortunately.
